Specification forming part of Letters Patent B10313378., dated August 9, 1864-.

-To'alt echo-in Iit may concern ne it known' um I, L'. Kimm eleventh,-

of Cuyahoga county, in the State of Ohio, have invented anew and useful Machine for Making Chains.; and I do herebydeclarethat the following isa full, clear, and exact description thereof, reference being had to the accompanyingdrawin gs, making part of this specification,

yand to the letters of reference marked thereon,

in which drawings- Figure l is a top plan view of 'my machine;

Fig. 2, a transverse vertical section of the saine taken on the line ma: of Fig. l. Figs..

chain from a single metal rod or wire canbeef-I iected by the operation of the machine alone.

.To enable others skilled in the art to makey and use my invention, I will proceed to describe it.

A represents the frame or platform to which the mechanism is secured. Nea-r the top of the machine, in proper hearings, is mounted the main shaft B, upon which are secured three double cam-wheels a', I), and c, by which the movements of the dies and other parts cutting, forming, and joining the links are contro1led, as will be hereinafter explained. On the end of shaft B is a gear-wheel, j, which imparts motion to shaft D, and from thence by means of the bevelgear to wheel F on shaft E. rlhe periphery of wheel F is pro- -vided'with a groove,extendin g part wayaround it. A portion of the periphery equal in length Y to the rod uit', Fig. G, which is to form one link,

has no'groove, or but a very slight one. Di- .rectly underneath Wheel F, and revolving in the saine vertical plane, is 'a duplicate wheel, F. (SceFig. 2 of the drawings.) The end of the wire or rod forming the chain is entered between these two wheels, and asthcy' revolve the rod is caught between those portions having but a slight groove, and fed forward through a hole in the side of the frame C for a distance equal to rod aft, at which point the and cuts ott' the wire c* for the first link.

further feeding in of the rodceases by virtue of the wheels `having" revolved to such a position that their grooved portions come'opposite the rod and their hold thereon released. At this time the cam c comes in contact with i lever c, the lower end of which, engaging with the chisele, Fig. 5, moves thelatter forward Immediately thereafter the projection 1 of'cam a operates-the lever a, which moves the sliding die f forward, by which the wire is forced against a corresponding die, j', Fig. 4,' which is forced down into proper Aposition at therequired time by'cam b, by which operation the rod is bent, as shown by bFig. 6. vImmevdiatelyafter this process the cam b, striking levervb, shoves forward the plunger g g, the hinged arms "h h of which, coming in contact with the rod b* on each side of the point,'wbere it is firmly heldbetween f and j", carries the ends of Zi* forward, and at thesame time iii- Ward toward each other', the. lattermovement being imparted by the converging movements -of arms h h impinging against the curved'sides of the frame, as shown in Fig. 5, by which -operation the rodis bent in the ferm show-n by ci?, Fig. 6. At this stage the cam a., striking the sliding frame k, Figs. 2 and 3, moving it forward, causing its rear portion, 7c', to enter a beveled recess in the upper portion of f', raising it, and thus releasing the link 0*, which is -then shoved-bodily forward by a further movement `of the die f, leaving it deposited with its ends in the recesses 1f r over the opening s, as indicated by blue linesin Fig. 5,

the ends ofc* in coming to this position being thrust through thebent portion of the preceding link, which is held upright in the opening s for that purpose by a spring-latch, s', working in the lower portion of `said opening s. A plunger, a', is then forced down .by the 'point 2 of cam a, which plunger striking the preceding link di, which, resting upon the arms of the unfinished link c?, as shown in red in Fig. 6, forcesthe end of the latter with d* down into the opening s, by which the ends of c* are bent and clasped around the upper portion of link di, the `link ci 'being atthc same time raised to a vertical position and carried down far enough to `occupy the position from which d* had been forced in the operation. As the cam c revolves,'a projectiom, upon its side engages under pin o of the arm a2",

which, being attached to plunger w, raises thelatter upout of the Way of the succeeding link and into a position for repeating its operation, as above described. The point 2 of cam a, as it continues to revolve, next strikes Vthe piv'oted levert/1.2 .at the'opposite side of completing the process of forming and atta'chin g a link. The process thus described is repeated twice at each-revolution of the shaft' B, the cams thereon *being* duplicated or double, as already stated, and as shown in Fig. 2. Thus the process or operation is made continuous.y bythe continued revolution of .the Shaft B. whereby link after linkis formed and added to the chain so long as the wire of which it is inadesfurnished to the machine. B-y this improved method of constructing and 4operating my machine I obtain one that-isl sim-ple, compact, and that 'performs its work 1n a most etlicicnt, rapid7` and satisfactory manner, andl by Whiclrthe labor and cost of producing thechain is greatly lessened..v

Having thus described my'invcntion and itsl operatlon, what I claim is- Constructing V a. chain ot'. the form` herein .represented from asingle rod or Wire by ,one continued process, by means of an automatic machine constructed, arrangetL'aIid having all -its parts 'operated subs'tantall y as described.
